After struggling a bit with my system, I managed to launch the ESC with a french Gemalto Smart Card & reader. Here is what happens. First I see a notification pop-up that tells me : Can't get UniversalXPConnect.TypeError: Components.classes['@ redhat.com/rhCoolKey;1'] is undefined Then when hitting "diagnostics", I get the following. SMART CARD DIAGNOSTICS REPORT ***Software Version Information*** Smart Card Manager Version: null System Versions: mozilla/5.0 (x11; linux i686; rv:16.0) gecko/20100101 esc/1.1.0-16 ***Active Smart Card Details*** Number of Smart Cards Detected: 0 ***Smart Card Activity*** No log file or log file has no data. Can someone tell me what all this means (probably that the reader or card is unsupported), however... Thanks P
